CRUSHING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 348,757, datedSeptember 7,1886.

Serial No.173,535. (No model.)

To all whom it may concern.-

Be it known that I, Ronnn'r MoGULLY, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inCrushing-lilachines, ofwhich the followingis a specification, referencebeing had therein to the accompanying drawings, wherein Figure 1 is avertical central section of a crushing-machine witheccentrieally-gyrating shaft, showing my improvements. Fig. 2 is a planof part of the top section or plate of the machine, showing bearing orboxes for the ball-fulcrum of the gyrating shaft and a crossseetion ofthe bolts for sustaining and vertically adjusting said boxes. Fig. 3 isa plan of part of the gear-wheel for imparting to the crushenhead shaftits eccentrieallygyrating motion, showing the fan-blades on its upperside for preventing entrance of dust to the bearings of said wheel andthe eccentric formed thereon. Fig. 4 is a vertical section on a line atright angles to the line of the section shown in Fig. 1, showing moreparticularly the construction of the chutes; and Fig. 5 is a sectionthrough line 1 1, Fig. 1.

My inventionhas relation to stone or other crushing machines, wherein isemployed an eccentricallygyrating crusher-head; and it has for itsobjects to so construct the parts of the machine that it is run oroperated with less power than formerly required; that the adjustment ofthe ernshenhead and shaft for varying the fineness of the crushing andfor taking up the wear of the crushing-faces is made from the top of themachine; that the eccen' tric driving-gear for the lower end of thecrushenhead shaft is oiled from the top of the machine; that dust ordebris is effectual] y excluded from the eccentric driving-gear hearing;that there is less frictional contact between the sleeve on the lowerend of the gyrating shaft and the eccentric bore of the driving-wheel,and that the crushed material is conveyed quickly from the machinewithout tending to lodge upon or clog up any portion of the chuteways.

My invention accordingly consists of the combination, construction, andarrangement of parts, as hereinafter described and claimed, havingreference particularly to an eccentricall y-gyratin g shaft andcrusher-head freely suspended from or wholly supported by the top of themachine by means of bolts or other suit-able devices having adjusting-nuts or mechanism for raising or lowering the shaft and crusher-head,to adjust the latter for altering the fineness of the crushing and fortaking up the wear of the crushingi'aces of the machine; to a tubulargyrating crusher head shaft having near its lower end lateral orificesor ducts leading to adjacent parts of the eccentric and its driving-gearand bearing of the latter, for effecting the oiling of said parts fromthe top of the machine, the hearing or box for the drivinggear having avalved outlet-duct for surplus oil, and also a draiirontlet; to adriving-gear having an eccentric bore, and upon its upper side a seriesof angular projections or blades surrounding said bore, for blowing orfanning away any dust or debris tending to gain access to the eccentricbore of the driving-gear; to a sleeve forthelower end of the gyratingshaft, which sleeve on its outside tapers in reverse directions from itshorizontal middle to its ends; and, finally, to a two-way chute the topor meeting edges of which form a sharp ridge for preventing depositionof crushed material thereon, and avoid choking or clogging up thechuteways.

In the drawings, A represents the frame or housing of the machine, ofpreferably a circnlar or cylindrical configuration, and is composed oftop plate or section, B, having feedopenings I), of crushingchamber 0,having crushing-faces c, of chute or exit-chamber D, and bottom plate,E.

F represents the gyrat-in g shaft; G, the crusher-head secured thereto;H, the driving-wheel having eccentric bore It, and in gear with a wheel,I, upon a suitable power'shaft, t.

The top plate or section, B, is provided with the usual or any suitablevertical central opening, 1), in which are located the boxes or bearingsIf for the ball-fulcrum f of shaft F. The boxes If are supported uponthe heads is of bolts K, placed, preferably, in vertical slots orrecesses b in the sides of opening I), as more plainly shown in Fig. 2.The bolts K pass upwardly through holesl in a plate or cross-bar, L, andare provided with nuts or other suitable devices, for impingementagainst plat-e L, to afford supports for the boxes ICO b and in turn forthe shaft F and the crusherhead G; The shaft and crusher-head have noother supports, as the lower end of the shaft does not rest upon a setor tramming screw, as has heretofore been the case, but merely entersthe eccentric bore of the driving-wheel H. (See Fig. 1.) As shaft F isfreely suspended or wholly supported from the top of the machine by itsball-fulcrum f, the shaft and crusher-head are easily gyrated and aneconomy in the amount of power required for operating the machine iseffected.

To raise or lower the shaft F and the crusher-head G, or to adjust thelatter for varying the fineness of the crushing, or for taking up thewear of the crushing-faces of the machine, the nuts 7; are Simply turnedor adjusted in the proper direction to slide the boxes If up and down inopening I), and the shaft and crusher-head following therewith, thedesired adjustment of the crusher-head is made.

The bolts K and their adjusting mechanism and cross-bar L serve thedouble purpose of freely or wholly supporting the shaft and crusher-headand for altering the adjustment of the latter from the top of themachine.

The shaft F is preferably made hollow, or

- has a bore, j", which extends downwardly to lateral openings ordncts,f located below the top edge of the hub of the driving-gear H, asshown more plainly in Fig. 1.

The oil is poured into the top of the shaft through an opening, Z, inplate or crossbar L, which opening is closed by a screw or removableplug, Z'-. Plate L is preferably made large enough to completely coveror form a cap for opening Z), to exclude dust therefrom and keep thebearing-surfaces of the ball-fulcrum intact. The latter, as well as thedriving-wheel, are oiled from the top of the machine, and, if preferred,at the same time. The driving-gear H has an elongated hub, 71', which,if desired, may be formed separately from the wheel, as shown. The hub hhas its bearing in a box, 0, formed on plate E, and is held in positionto support wheel H by means of an outside flange, h, resting upon thetop edge, 0, of box 0. Surrounding the edge e is an annular flange, 0

forming a corresponding]y-sh'aped gutter, 0*,

adjacent to the hub-flange 71 and from this gutter a duct, 0 leads downthrough the walls of box a to its lower edge and through its cap orcover e and is furnished with a stopcock, 0. If desired, the cap mayhave removable or screw plug 6 for a purpose hereinafter to bedescribed. The wheel H or its hub h has an eccentric bore, 71., for therecep tion of the lower end of shaft F, and by means of which theeccentricallygyrating motion is imparted to said shaft. The lower end ofthe latter is preferably provided with a suitable sleeve, M, held inplace by a washer-plate, m, and screw on on the bottom of the shaft.Sleeve M may be made or configured in any desired way, or, in otherwords, it maybe a straight cylindrical sleeve, as heretofore employed. Iprefer, however, to use a sleeve the outside of which is taperedtransversely from its middle toward its ends, as shown in Fig. 1, thedegree or inclination of the taper being the same or about that of theinclination given to the shaft F by the eccentric bore of thedriving-gear. Only a portion of the top and lower tapered parts of thesleeve M are at any one time in contact with the eccentric bore h of hubJ1 during the rotation of the latter or during the gyration of the shaftF, and the amount of frictional contact between sleeve M and eccentricbore h is thereby materially reduced without affecting the effectivenessof the machine.

The hearing or contacting faces of the shaft F, sleeve M, and wheel Hare oiled from the tubular shaft F, and this is accomplished insubstantially the following manner: \Vhen the lubricant is poured intoshaft F, the cock 0 is opened. The oil escaping from lateral shaftductsf falls upon the sleeve M and works its way downwardly between sleeve Mand eccen-. trio-bore h to fill the spaces above and below said sleeve,and thence works upwardly between hub 7t and box 0 until it reaches thetop edge, 6, between which and the flange 7: it works out and overflowsinto gutter e, and finally passes out through duct 0. As soon as the oilescapes from cock e", or before this occurs, the filling operation isstopped. The cock 0 is closed when the oil ceases to drip therefrom, anda supply of oil is then contained in box a for thorough lubrication ofthe sleeve and eccentric and driving wheel bearings during the operationof the machine. Any accumulations of thickened or gummy oil in box 0 mayfrom time to time be drained away by unscrewing or removing plug 6 Tofacilitate the upward passage of oil between box 0 and hub h the latter,preferably, is formed with outside vertical recesses, h", (see moreplainly Fig. 5,) of which any suitable number may be used.

The top of the hub of wheel H is closed by a cap or collar, N, which ispreferably loose upon shaft F and rests loosely upon the top of the hub.This cap is made large enough in diameter to extend over a series ofangular or other shaped wings or projections 01, formed on the upperside of the wheel H surrounding the hub eye or opening 71. As the wheelH revolves its wings or projections a fan the air about the upper partof the hub of said wheel, and as the cap N rests upon said hub andextends over the wings a it tends to direct the air-currents producedbythe latter in an outwardly direction or away from the wheel-hub. Thesecurrents blowing or directed outwardly from the hub of wheel H fan orblow from it any dust tending to gain access to the bore of the hub.Oonsequentl y its inner workin g-surfaces are kept free from foreigndirt or grit.

The chute chamber or section D is provided with two ways or chutes, d(1, arranged on opposite sides of the machine. The upper or meetingedges, d, of the chutes form a trans verse sharp ridge, (2 of the sameinclination as thatof the chutes, to prevent the lodgment of crushedmaterial thereon and provide for quick exit of the material from themachine without tending to clog on the chuteways.

From the ridge d and chuteways projects upwardly an annular flange, p,which is surrounded by a like flange, 1), depending from a sleeve, P,which may be secured in the usual or any suitable manner, as shown, toshaft F, to receive the crushing-faces G of the crusherhead G. I,however, prefer to cast sleeve P on said shaft. These annular flanges pptend to prevent dirt or dust passing into the chamber D beneath itschutes, as the crushed material falls upon the chutes outside of saidflanges.

The crusher'faces G may be constructed as desired, and are preferablyconnected to sleeve 1 by molten lead or metal keys p in the usualmanner.

' To firmly support the crusher-head G upon sleeve I, the latter ispreferably formed near its bottom with a shoulder, 11, upon which the 1crusher-head G rests.

The casting of the sleeve 1? upon the shaft F, in addition to the use ofthe molteirmeial connection for the crushing faces G and sleeve P. admitsof securinga crusher-head, the parts of which are firmly secured tothe shaft and to each other without fitting orfinishing. The chamber (1is formed near its bottom with a like shoulder, c, to support itscrushingfaces c, and to prevent the latter moving or rising in saidchamber they are formed near their upper ends with outside projectingflanges, 0 which fit into correspondingly-shaped adjacent recesses c inchamber 0."

If desired, two flanges may be formed on the faces 0 and two recessesmade in chamber 0, as indicated by dotted lines as, Fig. 1, to moreeffectually maintain said crushing-faces in place.

By the employment of the flanges c and recess c the advantage ofobtaining the full thickness of the crushingfaces at their top parts isobtained, and they are therefore not liable to break off. Said flangesand recess also prevent the upward crushing strains or pressure againstthe faces 0 falling upon the joint between chamber 0 and its top plate,B, and hence all tendency to loosening the bolts connecting said partsis avoided. The various sections of the frame of the machine aresuitably flanged, bolted, as shown, or they may otherwise be securedtogether, as desired.

In the drawings I have shown two bolts, K, for the boxes Ir of shaft F,and these bolts 10- eated between the boxes and the sides of the openingZ) in top section, B; but I do not limit myself thereto, as other meansshown and described in an application of even date here with, Serial No.173,536, may be substituted for said bolts.
